    range.intersectsNode

    Summary

    Obsoleto
    This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

    Returns a boolean indicating whether the given node intersects the range.

    Syntax

    bool = range.intersectsNode( referenceNode )
    

    Parameters

    referenceNode 
    The Node to compare with the Range.

    Example

    range = document.createRange();
    range.selectNode(document.getElementsByTagName("div").item(0));
    bool = range.intersectsNode(document.getElementsByTagName("p").item(0));
    

    Notes

    This method is obsolete; you should instead use the W3C DOM Range methods (see compareBoundaryPoints()).

    Warning: This method has been removed from Gecko 1.9 and will not exist in future versions of Firefox; you should switch to compareBoundaryPoints() as soon as possible.

    The following function can be used as replacement:

    function rangeIntersectsNode(range, node) {
      var nodeRange = node.ownerDocument.createRange();
      try {
        nodeRange.selectNode(node);
      }
      catch (e) {
        nodeRange.selectNodeContents(node);
      }
    
      return range.compareBoundaryPoints(Range.END_TO_START, nodeRange) == -1 &&
             range.compareBoundaryPoints(Range.START_TO_END, nodeRange) == 1;
    }
    

    Specification

    This method is not part of a specification.
